Sis-in-law problems...

So I am currently 13w and 3d pregnant and when my husband and I first found out we only told his dad his step-Mom and his little brother. Well his little brother had to go off and share the news cus about into my 6th week I got a text from step mom saying somehow the grandma and his sister found out and that grandma was happy for me but the sister was mad. She has a history of not being able to get pregnant I am 22 and she is 23 which I completely understand can be hard for her. But my last pregnancy (I miscarried 10w) my husband shared with her and she just snapped back saying you don't deserve to have a baby. Yes sometimes she can be a snooty b. So this time we wanted to wait till I made it to share with family into my second trimester. Honestly I'm in no mood to put up with anyone's feelings if your happy for me then good if not then F off. I could careless. My husband is the same way we just want to be surrounded by positive people. Is that wrong at all? I know she's my sis in law but my family doesn't do any of this crap
